SelbsttätigerKlappenverschlussfürKanaleinläufe.
Nach vorliegender Erfindung ist die infolge Gewichtswirkung selbsttätig sich schliessende Klappe für Kanaloinläufo nicht direkt am Gehäuse, sondern an dem einen Arm eines Doppelhebels gelagert, welcher letzterer am Gehäuse drehbar befestigt ist. Der andere Arm dieses Doppelhebels stösst nach einer gewissen Ausschwingung gegen einen Ansatz, wodurch die Drehbewegung des Doppelhebels arretiert und dieser bezw. der an ihm vorgesehene Anlenkpunkt für die Klappe. zum Drehpunkt für die letztere wird. Hiedurch wird das die Klappe zurückführende Gewichtsmoment infolge Verringerung des Hebelarmes kleiner und ferner infolge der seitlichen Verschiebung die Klappenöffnung grösser.
Auch werden beim Schliessen der Klappe die etwa anhaftenden Teile auf dem Gehäuse und der Klappe durch die schiebende Wirkung abgestreift, wodurch ein sicheres und vollständiges Schliessen der Verschlussklappe erfolgt.
In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt.
Fig. 1 stellt einen Vertikalschnitt, Fig. 2 eine Draufsicht bei abgehobenem Rost und Fig. 3 die Klappe mit dem Hebolwerk allein vor ; Fig. 4 und 5 zeigen die bisher ge-

Der Einlauftrichter c wird an seiner unteren Öffnung 11 durch die Klappe a verschlossen, die bei f an den Doppelhebel e gelagert ist. Letzterer ist bei a an den Trichter drehbar befestigt und durch den Anschlag i in seiner Drehbewegung begrenzt. Das Zurückführen der Klappe wird durch das Gewicht k bewirkt.
Strömt nur wenig Wasser ein, so wird die Klappe sich nur wenig öffnen, wobei d als Drohpunkt derselben anzusehen ist. Bei grösseren Wassermengen wird der obere Arm dos Hebels e an den Anschlag i anstossen und die weitere Drehbewegung dieses Hobels verhindern. Es kommt nun f als Drehpunkt zur Geltung. Wie ein Vergleich der Fig. 3 und 5
EMI1.2
da der wirksame Hobelarm kleiner ist. Daher wird die Klappe nicht mit solcher Wucht gegen den Trichter zurückgeschlagen und eine Beschädigung dieser Teile vermieden werden.

Automatic flap closure for sewer inlets.
According to the present invention, the flap for duct inlet, which closes automatically as a result of the effect of weight, is not mounted directly on the housing, but on one arm of a double lever which is rotatably attached to the housing. The other arm of this double lever hits after a certain oscillation against an approach, whereby the rotary movement of the double lever is locked and this respectively. the articulation point provided on it for the flap. becomes the fulcrum for the latter. As a result, the weight moment returning the flap becomes smaller as a result of the reduction in the lever arm and, furthermore, as a result of the lateral displacement, the flap opening becomes larger.
Also, when the flap is closed, any adhering parts on the housing and the flap are stripped off by the pushing action, as a result of which the closure flap closes safely and completely.
The drawing shows an embodiment of the subject matter of the invention.
1 shows a vertical section, FIG. 2 shows a plan view with the grate raised and FIG. 3 shows the flap with the lifting mechanism alone; 4 and 5 show the
EMI1.1
The inlet funnel c is closed at its lower opening 11 by the flap a, which is mounted at f on the double lever e. The latter is rotatably attached to the funnel at a and is limited in its rotational movement by the stop i. The return of the flap is caused by the weight k.
If only a little water flows in, the flap will only open a little, with d being seen as a threatening point. With larger amounts of water, the upper arm of the lever e will hit the stop i and prevent further rotation of this plane. Now f is used as the pivot point. Like a comparison of FIGS. 3 and 5
EMI1.2
because the effective cutter arm is smaller. Therefore, the flap will not hit back against the funnel with such force and damage to these parts will be avoided.
